hi
assuming that your numbers are in column B and has a header in B1
this formula(in B16) will give you the last number in the column.
=OFFSET(B2,COUNTIF(B2:B15,"0")-1,0)
this formula will give you the "weight lose" by subtacting the "start
weight" form the last number in the column.
=B2-OFFSET(B2,COUNTIF(B2:B15,"0")-1,0)

adjust cell references to suit your data.

I'm tracking weight loss.
In one column I have a list of #'s.
The top # is the beginning weight.
Each # under the beginning weight is from succesive weigh-ins.
I want a cell at the bottom of the column that displays the total weight loss.
How do you make the cell recognize the last weigh-in entry in stead of the
previous one?
